What metamagic feats, spell combinations, or devious little sparks of creativity work awesome with Mirage Arcana and/or make it a more effective spell?
I've been considering Spell Perfection Mirage Arcana for an upcoming illusionist PC, but I'm having a hard time convincing myself that the spell really benefits from it. Sure, the DC to disbelieve goes up, but is that really all I can squeeze out of this? Or is there some killer feat/spell/class ability combination I've not thought of?
